Finding Min Value in array with changing condition

Hello guys,

I got a matrixs which are like ;

a=randi([0,1],1,5)

cost=[6739,10355,7650,5219,5776]

in this changable conditions I want to find the min value.

For example;

a= [1 0 0 0 1]

cost=[6739,10355,7650,5219,5776]

min cost = 5776 according to matrix a

tf      = a == 1    % create a logical array
temp    = cost(tf)  % logical indexing to retrieve certain values
mincost = min(temp) % use a dedicated function to find th minimum value

I leave it to you to make this a single statement!
